Patented Feb. 11," 1930 PATENT OFFICE i AGUSTIN BnNAvEN'r crimes, or SAN BAUDILIO DE LLOIBREGAT, SPAIN HoMIDIFIER iron, INTERNAL-COMBUSTION ENGINES Application filed June 10, 1927, Serial No. 197,792, and in Spain April 16, 1927.

This invention relates to improvements in humidifier for internal combustion engines, the object of the invention being to provide a device of this character by meansof which water, air and gasoline are intermingled in the proper proportion to produce a combustible mixture rich in oxygen and of maximum efficiency.

Other objects and advantages of the invention will appear as the ceeds.

In the drawing accompanying this specification, which drawing is illustrative only,

Fig. 1 is a central longitudinal section through a device embodying the features of the present invention;

a Fig. 2 is a conventional side elevation of an engine with the improved deviceapplied thereto; and

Fig. 3 is a detail side view of a connecting member employed in assembling the device between the carburetor and the suction pipe of the engine.

The same characters of reference designate 25. the same parts in the different figures of the drawing. 1

Referring to the drawing, 1 designates an elongated receptacle formed in several parts, three being shown in the drawing, the individual parts being threaded together, as illustrated. The receptacle is divided interiorly thereof by partitions 2 and 3, forming three adjacent compartments 4, 5 and 6, eachcome partment communicatingwith the next succeeding one by openings 7 and 8 formed in the partitions. The compartment 6 communicates with a neck 9 which is adapted to be connected withthe suction pipe of the en- 49 i vhile the compartment 4 at the opposite end of the receptacle communicates with a bell shaped mouth 10, the communication being controlledby means of a butterfly valve 11 description pro-.

ine in the manner hereinafter described,

trolled. As shown in Fig. 2, this inlet port is intended to communicate with the cooling radiator by means of a tube 18. It may, however, communicate with any other con veniently disposed water supply.

As shown inFig. 2, theneck 9 is connected to a pipe 17 which in turn communicates with the fuel suction pipe of the engine at a point near the carburetor. The device illustrated in Fig. 3 forms a convenient means for connecting tube 17 to the, suction pipe. This device is provided with a flat portion or plate 21 corresponding in shape to the connecting flanges of said pipe and tube, and in which plate a central opening 22 is formed and adapted to coincide with the suction pipe. The plate 21 mergesinto a tubular exteriorly threaded portion 24 adapted for connection with the tube 17 said tubular portioncommunicat'ing by a passageway 23 with the opening 22 in the plate. By theemployment of this device, theapparatus can be attached to existing engines without any constructional changes.

The operation of the device is asfollows: During the periodof suction of the engine, a vacuum is produced in the receptacle 1 which causes the valve 14: to unseat, thereby permitting the entrance of water on the tube 18 through the valve chamber 13 and into the compartment 4:. At the same time air will enter 1 the said compartment through the mouth 10, th'e quantityof air admitted dependingupon the position of the butterfly valve 11. The mixtureof air and water in compartment 4 will be forced through the orifices 7 in the partition 2- and through the orifices 8 in partition 3, the complete mixing of the water and air being facilitated by the provision of the cone-shape projection 25 extending into chamber 5 from the partion 3.

"Owing to the factthat the receptacle '1 is made up of a number of parts which can be separated by unscrewing one from the other, it can readily be taken apart for cleaning purposes,*or for repairs. It will be understood, of course, that while the device as shownherein is illustrated in connection with a motor car'engine, it may be applied to any other typeof internal combustion engine. It i.

will also be understood that I do not limit my invention to any particular size or shape of the component parts, nor to any particular manner of connecting them together, the

essential features of the device being a receptacle which communicates at one portion thereof with the suction pipe of the engine and at other portions thereof with the atmosphere and with the radiator or other vessel containing water, so that a supply of air and water to form an effective mixture may be taken in at the same time that the gasoline is taken from the carburetor. Preferably,

and as shown in the drawing, the air and 1 water are admitted to the receptacle at right angles to each other, whereby an intimate mixture is produced within the receptacle, the partitions provided with small openings through which the mixture of water and air passes being for the purpose of still further enhancing the mixing together of these elements during their passage through said I claim as my invention I 1. A moisture supplyingdevice for internal combustion engines, comprising a hollow member, partitions dividing the interior of said member into two end-chambers and an intermediate chamber, one of said end-chama bers being adapted for communication. with the fuel suction pipe of the engine and the opposite end-chamber being in communication with the atmosphere, a valve housing in communication with said last end-chamber in Q a direction at right angles to the atmosphere communication, a normally closed springplfessed valve in said housing, a manually oparable valve for controlling said atmosphere, communication, said partitions being proivided with perforations wherebyadjacent chambers are in communication, said perforations being so disposed that the fuel suctionof the engine will open said springpressed valve and cause a stream of moisture and a stream of air to intersect and mingle in the atmosphere communicating chamber and be drawn thence through the remaining chambers to the fuel suction pipe.

" 9. A moisture supplying device for intermember, partitions dividing the interior of said member into two end-chambers and an intermediate chamber, one of said end-cham bers being adaptel for communication with 55 the fuel suction pipe of the engine and the opposiite end-chamber being in communication with the atmosphere, a valvehousing in communication with said-last end-chamber in a directional; right angles to the atmosphere communication, a normally closed spring-pressed valve in said housing, a manua ly operable valve for controlling said atmosphere communication, said partitions be-v a ing provided with perforations whereby adnal combustion engines, comprising a hollow perforations being so disposed that the fuel suction of the engine will open said springpressed valve and cause a stream of moisture and a stream of air to intersect and mingle in the atmosphere communicating chamber and be drawn thence through the remaining chambers to the fuel suction pipe, one of said partitions having a centrally disposed coneshaped projection between its perforations, said projection extendin in a direction pposite to the direction of movement of said mingled streams of air and water.

In testimony whereof I have signed my name to this specification AGUSTIN BENAVEN T CAMPS.
